My face.

A conversation that took place. 

Friend: Are you going to Phish this summer?

Me: Uh, yeah. 

Friend: Yeah, I'm trying to get tickets for Red Rocks. 

Me: You should. Go on StubHub. It's worth it. 

Friend: Yeah, I probably will. Did you pay face?

Me: Yes, I will be paying with my face. Consider it melted.
